"List" - what is it, definition of the term
An ordered collection of elements, indexed by position and permitting duplicate values, constitutes a fundamental data structure that enables sequential access, insertion, deletion, and iteration; it can be realized through array‑based storage for constant‑time indexing or via linked nodes for efficient insertions and deletions, and serves as a core abstraction in most programming languages.
Detailed information
An ordered series is a fundamental data construct that stores elements in a specific sequence, allowing direct access by position and supporting operations such as insertion, removal, and iteration. Elements retain the order in which they are added unless explicitly reordered, which makes the structure suitable for representing hierarchical or chronological data.
When applied to zoological classification, a collection can efficiently organize information about rodent species, particularly those belonging to the genera Rattus and Mus. Each entry may include taxonomic rank, geographic distribution, typical habitat, and notable physiological traits. This approach enables systematic retrieval and comparison across multiple species.
Key attributes of a rodent entry in such a collection:
- Scientific name – binomial designation used universally in taxonomy.
- Common name – widely recognized term for lay audiences.
- Distribution range – continents, countries, or specific ecosystems where the species is native.
- Habitat preference – urban, agricultural, forested, or subterranean environments.
- Size metrics – average body length and weight, facilitating ecological modeling.
- Reproductive profile – litter size, gestation period, and breeding frequency.
- Behavioral notes – foraging patterns, social structure, and disease vector potential.
Example of a detailed enumeration of selected species:
-
Rattus norvegicus (Norwegian rat)
-
Rattus rattus (Black rat)
-
Mus musculus (House mouse)
- Distribution: global, thrives in human settlements.
- Habitat: walls, cupboards, fields.
- Size: 7–10 cm body length, 15–30 g weight.
- Reproduction: up to 8 offspring per litter, gestation 19 days.
- Behavior: rapid breeders, high adaptability, laboratory model organism.
-
Mus spretus (Algerian mouse)
- Distribution: Mediterranean basin, North Africa.
- Habitat: shrublands, cultivated fields.
- Size: 8–11 cm body length, 20–35 g weight.
- Reproduction: similar to house mouse, but lower litter size.
- Behavior: less synanthropic, valuable for comparative genetic studies.
Utilizing an ordered series to catalog these rodents supports precise data handling, facilitates statistical analysis, and aids in pest management strategies. The structure’s inherent ability to preserve insertion order ensures that chronological observations—such as population trends or emergence of resistance—remain intact throughout processing.
